Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Oil Filter

Tools Required: Oil filter wrench, new oil filter, oil catch pan.
Remove the oil filter using the oil filter wrench.
Inspect the old filter for signs of wear or damage.
Install the new oil filter, ensuring the rubber O-ring is lubricated with fresh oil before sealing.

3. Address Oil Leaks

Tools Required: Socket set, torque wrench, gasket scraper.
Identify the source of any leaks (valve cover gasket, oil pan gasket, etc.).
Remove the affected component (e.g., valve cover) by unbolting it and scraping off old gasket material.
Install a new gasket and torque to manufacturer specifications (refer to the service manual for specific torque values).

4. Replace Engine Oil

Tools Required: Socket set, oil catch pan, funnel.
Drain the old engine oil by removing the oil drain plug and allowing it to fully drain into the catch pan.
Replace the oil drain plug and torque to manufacturer specifications.
Refill the engine with new oil using the recommended oil type (check owner’s manual for specifications).

5. Perform Engine Tests

Reconnect the battery.
Start the engine and allow it to run for a few minutes while checking for leaks.
Monitor oil pressure and check for any unusual noises.
